Use the AC power cord packaged and supplied with the Cage/BackPack. For systems
shipped to countries that utilize a 110–130-volt power system, the power cord is rated
at 15 amps. Systems shipped to countries with a 208-volt power systems are
packaged with power cords rated at 10 amps. Older model BackPacks utilized 10
amp-rated power cords that are NOT approved for use with current model BackPacks
on 110–130-volt power systems. The standard 10 amp power cords are acceptable
for use with the Fiber Transceiver. Refer to the Safety Guidelines on page 7 for more
information.
NOTE: The maximum steady-state current draw of a single fully loaded Cage ranges
between 6 and 8 amps at 120 VAC, based on the level of user activity. The
peak initial current draw is 12 amps. (See Table 3 Power and Cooling
Requirements – R1200 on page 36 for more information.) If you are placing
multiple Cages on a single power circuit, make sure that the circuit can safely
handle the combined currents of all the equipment. Therefore, if you place two
Cages on a single branch circuit, it must be able to support a peak current of
25 amps at 120 VAC.
BackPack Configuration and Operation
R4300 BackPack
By using a range of hot-swappable modules, the R4300 BackPack provides a wide
range of options for C/Port and I/Port connections to Blades and to the network.
Modules can be installed either when the Cage is installed, or when the Blades are
installed. Because these modules provide all the data I/O for the system, cabling
cannot be completed until these modules are in place.
The R4300 accepts the modules as shown in the positions in Figure 19.
CAUTION: Make sure your power strips, power grid, and circuit breakers
can safely provide the required current. Ensure that any extension cords
used meet local safety regulations and fire codes. When specifying
uninterruptible power supplies (UPS) be sure to include the Fiber
Transceiver peak current draws in your calculations to ensure the UPS
has adequate capacity.
CAUTION: To avoid equipment damage and potential personal injury,
always install the Cage (with assembled BackPack) in the rack before
installing any Blades in the Cage.
